The 61 strains had been divided into 9 species in accordance with the classification of Kloos & Schleifer. When S. aureus and the coagulase-negative staphylococci were examined, they contained iso-C15:0, anteiso-C15:0, C18:0, and C20:0 as main fatty acids. There was no marked difference in the cellular fatty acid composition between any two staphylococcal species. The percent cellular fatty acid composition of each species was regarded as one of the quantities of continuity and subjected to the analysis of variance by the unary configuration method. As a result, S. capitis, S. cohnii, S. epidermidis, and S. xylosus seemed to have a cellular fatty acid composition a little different from that of any other species. When similarity values among all the strains were calculated, they were 0.89 or more and made it possible to divide all the strains into two large groups at the similarity value of 0.90. In the one group the iso-C15:0 was a characteristic fatty acid. In the other group the anteiso-C15:0 was a characteristic fatty acid. To the first group belonged S. hyicus and S. lentus. To the second group belonged S. cohnii, S. epidermidis, S. haemolyticus, S. hominis, S. saprophyticus, and S. warneri.

The constituents of the water-soluble fraction of fish meal were suspected to be the cause of this lesion. Of them, histidine, histamine and nucleotides were examined. When added to milk casein and heated, histidine appeared to be the most toxic. It seemed, however, that histamine and IMP (inosine 5'-monophosphate) might be less toxic even when treated in the same way a histidine. Feeding of a large amount of histamine alone resulted in giving rise to a much disturbed profile of body weight gain, while a low incidence of gizzard erosion was observed in this case. Both heated fish meal and a heated mixture of casein and histidine were easily reduced in toxicity by acid hydrolysis. The latter was more sensitive to this treatment. On the contrary, papain had an action to diminish the toxicity of heated fish meal at all. Even after treated with papain, the heated casein-histidine mixture was still effective to induce gizzard erosion. These results might have come from different structural changes caused by heating of the two samples.</p>","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"21 1","pages":"52-60"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18257074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was little difference in the infective titer of HC virus estimated between the END method performed by the established technique and the same method by the conventional technique with test tubes and swine testicle (ST) cells. Besides, there was a high correlation between the neutralizing antibody titer measured by the one technique and that measured by the other. The coefficient of correlation was r = +0.948 in this case.
